Description
Jet vetoes are important tools that can be used to separate hard processes. A commonly used variable in which jets are identified and vetoed is the transverse momentum of a jet. It can also be useful to vary the tightness of such cuts depending on the rapidity of a jet depending on the focus on central or forward jets. This naturally leads to a class of such variables related to the leading jets transverse momentum weighed by some rapidity dependent function. Here we explore various types of rapidity dependent jet veto variables.
Applying tight cuts on such variables requires resummation of large logarithms, which can cause fixed order predictions to be unphysical. Here we present cutting edge partial N3LL + NNLO results for the Drell-Yan process in 2 rapidity dependent jet veto variables. These predictions act as a test for SCET and can be used to probe into the properties of QCD radiation.
